A spider that feeds indirectly on vertebrate blood by choosing female mosquitoes as prey.
Spiders do not feed directly on vertebrate blood, but a small East African jumping spider (Salticidae), Evarcha culicivora, feeds indirectly on vertebrate blood by choosing as preferred prey female mosquitoes that have had recent blood meals. Experiments show that this spider can identify its preferred prey by sight alone and by odor alone. When presented with two types of size-matched motionle...
متن کاملNorth American Seed-harvester Ants
■ Abstract Seed-harvester ants are a dominant and conspicuous insect group throughout arid portions of the southwestern United States and northern Mexico, and they include ∼75 species. Intense study in the late 1970s and early 1980s led to the paradigm that interspecific competition for limited seed resources is the primary factor that structures seed-harvester ant communities. This review atte...
متن کاملInteractions between the Social Spider Anelosimus Studiosus (araneae, Theridiidae) and Foreign Spiders That Frequent Its Nests
Because competition for resources generally leads to the spatial exclusion of species using similar resources, it is surprising that foreign spider species are frequently observed in or near the nests of the social spider, Anelosimus studiosus (Hentz 1850) (Theridiidae). In this study, we quantified the frequency of A. studiosus-foreign spider co-occurrence and completed experiments designed to...
متن کاملGenetic caste determination in Pogonomyrmex harvester ants
Division of labour between reproductive queens and sterile workers is a hallmark of insect societies and an important component of their ecological success (Hölldobler & Wilson, 1990). In ants and other social Hymenoptera forming large and complex societies, reproductive division of labour is generally associated with marked morphological differences between the queen and worker castes. These d...
متن کاملEffect of Interactions between Harvester Ants on Forager Decisions
Harvester ant colonies adjust their foraging activity to day-to-day changes in food availability and hour-to-hour changes in environmental conditions. This collective behavior is regulated through interactions, in the form of brief antennal contacts, between outgoing foragers and returning foragers with food. Here we consider how an ant, waiting in the entrance chamber just inside the nest entr...
